Amorphous Calcium Aluminate

CSA cement is a special cement with high strength, rapid setting time and low shrinkage. The main minerals of CSA cement is dicalcium silicate (C2S) and calcium sulfoaluminate (C4A3S). It is widely used to chemical construction materials such as dry-mix mortars, shot concrete, concrete repair and etc.

Amorphous Calcium Aluminate Details:

The mineral of amorphous calcium aluminate (non-crystalline calcium aluminate) is C12A7. The alumina content is about 50%. However, the appearance of amorphous calcium aluminate is different from crystaline calcium aluminate or CA. It looks like greenish (or a little blue color mixed) semi-transparent beads. Generally, the grains are ground into fine powders. The Amorphous calcium aluminate powder and OPC (ordinary Portland cement) and CSA cement are formulated into Rapid-hardening Mortar and Self-leveling mortar etc. With good performance of rapid strength and little dry shrinkage.

Application of the Amorphous Calcium Aluminate:

Shotcrete

Concrete accelerator

Rapid setting, rapid hardening cement

Concrete ground hardening

Rapid-hardening Mortars and Self-leveling mortars etc.
